We first estimate the number of Italian users active on Twitter in the last year by filtering the Italian flow of Twitter. We show that our filter misses about the 6.86% of the Italian flow, while 86.80% of the selected tweets belongs to the Italian

We perform a temporal analysis of the Twitter stream to investigate the evolution of unique events based on the burst of popularity of associated hashtags. We derive a classification of events according to the different patterns corresponding to the

In this paper, we study how to detect the most influential users in the microblogging social network platform Twitter and their evolution over time. To this aim, we consider the Dynamic Retweet Graph (DRG) proposed in Amati et al. (2016) and partiall

Community detection in graphs aims at identifying modules within a network and, possibly, their hierarchical organization by only using the information encoded in the graph modeling the network. Generally speaking, a community in a network is a subse

We propose a highly efficient and effective algorithm to estimate metrics on very large graphs that are based on the neighborhood function: examples of such metrics are the (effective) diameter and (effective) radius or the average distance. In order

Tree reconciliation is a general framework for investigating the mutual influence between gene and species trees according to the parsimony principle, that is, to each evolutionary event a cost is assigned and the goal is to find a reconciliation of

Topological and structural properties of social networks, like Twitter, is of a major importance in order to understand the nature of user activities, for example how information propagates or how to identify influencing accounts. A deeper analysis o

The study of the topological properties of graphs derived from social network platforms has a great importance both from the social and from the information point of view; furthermore, it has a big impact on designing new applications and in improvin

In this paper, we consider the representation and management of an element set on which a lattice partial order relation is defined. In particular, let n be the element set size. We present an \nradn-space implicit data structure for performing the f

In this paper, we study the stationary node distribution of a variation of the Random Waypoint mobility model, in which nodes move in a smooth way following one randomly chosen Manhattan path connecting two points. We provide analytical results for t
